Title: Phase difference detection circuit
Inventor: SEKO NOBUO
IPC: H02P29/00
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To provide a phase difference detection circuit that is capable of detecting the characteristics of the phase difference between the windings of a velocity generator and of determining whether they meet criteria or not automatically. SOLUTION: The sinusoidal waveforms of the windings of a velocity generator 1 are converted to output signals S2 and S3 of a rectangular wave in waveform shaping circuits 2 and 3. If the windings have no opposite phases, an output signal S4 of a D-type flip-flop(DFF) 4 takes its high level at a leading edge of the output signal S3 and its low level at a trailing edge of the output signal S2 when an output signal S6 of a one-shot flip-flop (OS) 6 has a generated pulse. The output signal S4 is converted in a smoothing circuit 13 into a mean voltage not depending on the rotating speed and is then outputted as an output voltage S13. A phase difference determining circuit 14 determines whether the output voltage S13 falls within the range of a reference phase difference from the lower-limit value or a voltage VrefL to the higher-limit value or a voltage VrefH or not.  If the phase difference falls within the normal range, a phase- difference detection output OUT2 takes its low level; if the phase difference falls outside the normal-range, however, this output OUT2 takes its high level.

Title: Surface roughness measuring device
Inventor: KANEKO KATSUMI
IPC: G01N15/08
Filed: 1990-11-16
Abstract: PURPOSE:To obtain an equivalent result as in the case when a tracer of a very small radius of curvature is used by adsorbing several kinds of molecules having different size on the surface of a sample, and by calculating its monomolecular capacity for obtaining fractal dimensions. CONSTITUTION:A sample is put in an adsorbing cell (c), and after heating and exhausting, a valve (e) is closed. Then, a valve G-5 is closed, and leaving a valve G-3 open, a valve G-1 or G-2 is closed. A value f-1 is opened at a constant temperature T1, and an adsorbate is introduced from a reservoir d-1, and then the valve f-1 is closed and pressure P1 is obtained. Then, the valve G-5 is opened to introduce the adsorbate into the cell (c), and after it has been balanced, the pressure P2 is measured. From the pressures PI, P2 and the volume of respective parts, the molar number MO of the sampled adsorbate and that M1 of the adsorbate remained in the gaseous phase after adsorption are obtained. The difference M0-M1 denotes the amount of adsorption at the pressure P2. Since the saturated vapor pressure PO is determined by the temperature T1, the amount V of balanced adsorption and the relative pressure x of the vapor is obtained from x=P2/P0. By repeating similar operations for the various pressures, and from the results obtained, monomolecular capacity m is determined. Then, the same procedure is carried out for the other reservoirs.

Title: Semiconductor device
Inventor: HISAE KENJI
IPC: H03K19/096
Filed: 1989-11-30
Abstract: PURPOSE:To quickly change the level of an output signal by changing the level of the control signal, which is supplied to the gate of an N-channel transistor TR, at a timing earlier than the signal of a bit line. CONSTITUTION:A data line DL is precharged by a precharging circuit 1, and the precharged data line DL is caused to fall in accordance with a data input SIN by an array circuit 2. At this time, a control signal SCO which has the level changed at a timing eariler than a signal SDL of the data line DL is supplied to the gate of an N-channel TR 4 which resets the level of an output line OL, and the N-channel TR 4 is switched off before a P-channel TR 3 is switched on. Thus, a signal in the high level is outputted to the output line OL by the switching characteristic corresponding to the threshold of the P- channel TR 3 when the level of the signal SDL of the data line DL falls.

Title: Multi-electrode type surface acoustic wave filter
Inventor: TANAKA TOSHIHARU
IPC: H03H9/145
Filed: 1993-12-09
Abstract: PURPOSE:To obtain a sufficiently large out-of-band suppression degree and to reduce a ripple in a band by setting up the maximum number of electrode combs weighted by an apodizing method to a range of 50 to 130 combs. CONSTITUTION:Two comb line receiving electrodes 2 are formed on a piezoelectric substrate 1 consisting of LiTaO3, LiNbO3, etc., and mutually connected in parallel. Three comb line transmitting electrodes 3 are mutually connected in parallel. The electrodes 2, 3 are alternately arranged in parallel in a surface acoustic wave propagating direction. Logarithmic weighting is conducted by changing the number of electrodes constituting this filter. Reflectors 4 are arranged on both the ends of these electrodes 2, 3 in the surface acoustic wave propagrating direction. Weighting is conduccted by changing the length of respective digits of the electrodes so that an envelope 5 is formed in each electrode 2. The generation of a ripple can be suppressed by limiting the maximum number of combs weighted by the apodizing method to 50 to 130 combs. For the similar purpose, a distance L between the electrodes 2, 3 is set up to L=(.05+alpha).lambda, provided that n is an integer >=0, alpha=0.26 to 0.5 and lambda is wavelength.

Filed: 1988-12-06
Abstract: PURPOSE:To attain high speed operation by connecting a connecting point between a switch means connecting to an output terminal of a current/voltage conversion circuit and an input terminal of a voltage/current conversion circuit and an input terminal of the voltage/current conversion circuit to a constant level via a capacitor. CONSTITUTION:A switch means 4 is connected between an input terminal of a voltage/current conversion circuit (comprising transistors (TRs) 5a,5b) and an output terminal of a current/voltage conversion circuit (comprising TR 3) and the connecting point between the switch means 4 and the input terminal of the voltage/current conversion circuit (comprising the TRs 5a,5b) is connected to a constant level via a capacitor 17. Thus, the capacitor 17 stores a voltage in relation to the current when the switch means 4 is interrupted and gives it to the voltage/current conversion circuit (comprising the TRs 5a,5b) and a current the same as that inputted from the current input terminal 1 flows to each drain of the TRs 5a,5b. Thus, the entire circuit acts like a pipeline to attain high speed operation.

Title: Pillow of free size for ankle
Inventor: OTA KUNIO
IPC: A47C27/00
Filed: 1987-12-09
Abstract: PURPOSE: To eliminate the fatigue of feet by making a wall part with the internal wall part of a through hole of each ankle pad free to expand to facilitate mounting on ankles. CONSTITUTION: A through hole 2 is provided at the center to let an ankle pierce it. A radial cut part 31 is provided in the internal wall part 3 of a ring block body 1 of the body of ankle pads comprising a ring-shaped soft polyurethane foam to form a freely expandable wall part. When a user puts his ankle through the through hole 2, the cut part 31 is deformed by a pressing force to make a buffer body. This enables easily fitting of ankles into the ankle pads regardless of the size of the ankles while serving to hold the ankles fit. Thus, when the user fits his ankles into the through holes 2 at the center of the ankle pads and lies on the back, foot parts are positioned slightly raised by the thickness of the ankle pads above a floor surface thereby achieving smooth circulation of blood to the foot parts.

IPC: A61M25/00
Filed: 1991-10-29
Abstract: PURPOSE:To prevent the leakage from the fine interstitial characteristic of an elastomer and to obtain the contrast effect in diaphanoscopy by X-rays by laminating and forming a leakproof layer with a material having the interstice denser than the interstitial characteristic between the material particles of the elastomer of a bulging part and forming a contrast medium layer in the bulging part. CONSTITUTION:The leakproof layer 3 covering the elastomer layer 2' is laminated and formed with the material having the interstice denser than the interstitial characteristic between the material particles of the elastomer constituting the bulging part 2 in the bulging part 2 known as balloon or cuff formed in a catheter A for medical use. The contrast medium layer 5 consisting of the contrast medium exhibiting a contrast effect at the time of X-ray contrast inspection is laminated and formed on the bulging part 2. Since the leakage of hot fluid is obviated in this way, the specified expansion state can be maintained before the removal of the catheter and since there is no need for injecting the contrast medium at the time of insertion of the catheter by the disphanoscopy using the X-rays, the adverse effects that the injected contrast medium exert on the treatment are entirely eliminated.
